Jack Singleton joined the Warriors Academy ahead of the 2014/15 season.
Singleton was yet another youngster who was handed his Warriors debut out in Russia against Enisei-STM in October 2016, in what proved to be a remarkable season for the young hooker as he made 20 appearances.
He made his Premiership debut against Northampton Saints in November of that year, before going on to make ten league appearances and playing in every European Challenge Cup and Anglo-Welsh Cup game throughout the season.
His impressive campaign saw him named as the Club's Young Player of the Season before being called up to an England training camp - and he was subsequently picked for England to take on the Barbarians at Twickenham, where they won 28-14 in May 2017.
He was then called up for England's tour of Argentina in June but despite being named on the bench for the two Tests in South America, he didn't get on for his first international cap.
Singleton signed a first-team contract ahead of the 2017/18 season.
The front row was a regular for Worcester Cavaliers in his earlier days at the Club and was also selected for England Under 18s.
In the summer of 2015, the youngster had a spell at Saracens RFC in New Zealand before returning to play his first senior game in a 2015/16 pre-season fixture against Saracens.
In the 2015/16 campaign, Singleton was dual registered with Nottingham Rugby, scoring a try on his debut in the British & Irish Cup against Cornish Pirates, while also impressing for Worcester Cavaliers before earning a call-up for England Under 20s.
He stole the show in the Six Nations with a magnificent four-try performance as England beat Italy 42-7 and later helped them to the World Rugby Under 20 Championship title in June 2016.
The hooker used to play rugby at Oaklands College and St Albans before joining the Saracens Academy set-up where he progressed from the Under 16s right up to becoming captain of the Under 18s. Singleton also captained Oaklands College first-team and represented Hertfordshire at senior level.
The youngster began his career as a centre then became a flanker at St George’s School in Harpenden before turning his hand to hooking.
